No matter how easy the CB make monetary conditions they can't generate that required boost to activity which would be reflected in a 2% inflation
This is critical to try understand. The 'desired' 2% inflation rate is a peculiarity.
It is all well and good in a stable economic environment to pursue such a policy.
But we are not in a stable economic environment, the global economy has had a massive shock.
Perhaps targeting a 10% or 20% inflation rate would be more apt in fighting off a deep prolonged deflationary period?
There is also a simple view of what inflation is - increase the money supply and prices will begin to rise as more money chases fewer goods.
This is too basic. It is evident in asset prices like fixed quantities of stocks, or slow production of housing. But technological advances in science, particularly with food production, means we live in times of abundance. In a globalised economy the supply chains are vast ensuring a much feared toilet roll shortage never materialised with the outbreak of Covid.
The digitalisation of much of what we consume is also a leading factor in deflation.
There was a time I would spend 0.30punts on a bus trip into town to flick through the record albums pressed on vinyl, in cardboard sleeve, wrapped in cling film. All the production, design, distribution, retail is gone. Replaced by digital versions, much more economically efficient with technological advances and the Internet are ripping through industry after industry.
Here is a theory, with the good ship human economy owing itself some three times more than it values itself, CBs should
raise interest rates to induce an inflationary effect.
Huh?
Yes, raise interest rates and the cost of borrowing will rise, those companies that strategise on increasing market share by taking on more debt will feel their balls being squeezed in the short to medium term. In the medium to long-term it will open the door for market competition entrepreneurship. But with less money (or more expensive money) chasing greater market share, only those with healthy balance sheets can compete and sustain themselves, driving out inefficient debt-ridden monopolists.
Of course there will be a cost to all of this, inflation - but that is the aim of CBs.
In a world where money had been reduced to its essential function of being a medium of exchange the CB will be endeavouring to ensure that there is no hoarding of money - if necessary by negative interest rates even for the populace.
Negative interest rates will induce hoarding, in cash.
If I have €100 in a bank account and in a years time it will be €98. I will keep my €100 in cash, it will still be €100 in a years time.
I see a brave new world where it would be perfectly consistent for the CB to be charging punters 4% on their money whilst banks are paying 2% on deposits and entrepreneurs are paying 5% to bank
I see the end of retail banking. In a world of CBDC and the Internet, if the prevailing interest rate is 5%, why would I borrow 10% from a retail bank? There is simply no need for them if a CB can deposit money into my account online at 5%.
